23 Claims. (Cl. 101394) This invention relates in general to type forms or chases employed in clamping type bodies together, having for its main object the provision of a device of the kind described of a simplified, more eflicient design and construction that will eiect a substantial saving in time and labor in securing type bodies within the chase.

Another object is to provide a chase with novel simplified means for operatively binding or locking type bodies within the said chase.

A further object is to provide a chase adapted to be operated by the application of a single means for binding or locking the type bodies therein preparatory to printing therefrom.

It is also an object of the invention to provide a type form or chase of generally improved construction, whereby the device will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and e'icient in its use.

Figure 1 is a top plan view of an embodiment of the invention;

Figure 2 is an enlarged, fragmentary sectional detail view of parts taken on line 2 of Figure 1;

Figure 3 is an enlarged, fragmentary sectional view taken on line 3 of Figure 1;

Figure 4 is a fragmentary plan view of details employed in a modified form of the invention, showing a locking or clamping position of the quoins;

Figure 5 is a fragmentary plan view of the device illustrated in Figure 4, showing a, different position of the quoins and coacting parts;

Figure 6 is an enlarged, fragmentary elevational view, partly in section taken on line 6 of Figure 4, illustrating the link or toggle-joint construction employed in the embodiment shown in Figures 4, 5; and

Figure 7 is an enlarged, fragmentary elevational view, partly in section taken on line 1 of Figure 4.

For the purpose of illustrating the invention we have shown in the accompanying drawings two forms thereof which are at present preferred by us, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that thervarious instrumentalities of which our invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

With more particular reference tothe drawings wherein similar characters of reference indicate corresponding parts in the preferred forms of the invention, I I designates a frame within which a pair of slidable or adjustable members or quoins I2, I3 are operatively arranged. On the reduced end I4 of the quoin I2 a pair of links I5 are pivotally secured by a pin I6 fastened thereto. 'Ihe links I5 are hingedly connected to two other pairs of links I'I and I6 respectively, by means of a pin I9 secured thereto as best shown in Figure 2, a washer 2| maintaining said last mentioned pair of links I1 in spaced relation. The assembly of links and coacting details above described form substantially a toggle-joint construction for operating the quoins of the device as will hereinafter appear.

The links I8 are pivoted to projecting pins or trunnions 22 of a small block or nut 23 having a hole 24 through which the reduced threaded stem 25 of an adjusting screw 26 is passed, the said block 23 being secured to the threaded stem 25 by the nuts 21, 28. The body portion 29 of the adjusting screw 26 is threadedly engaged in a hole 3| formed in the frame I I and has an angular head 32 adapted to be received in a socket wrench or key (not shown) for moving the quoins I2, I3 in the normal operation of the device.

The quoins I2, I3 as clearly shown in Figure 1, are each provided with a plurality of inclined surfaces 33, which are adapted to slidabfly coact with corresponding inclined surfaces 34, formed on a pair of bars 35, 36 which may be considered as a component part of the quoins I2, I3 and which directly engage the type forms (not shown) within the interior of the frame II. When the angular head 32 of the adjusting screw 26 is engaged by a socket wrench or other suitable means, the turning of the said screw 26 in a clockwise direction will advance the block 23 and links I8 towards the center of the frame II, thereby angling the other links I5, I'I into alignment or parallelism and, consequently, sliding the outer members I2, I3 o-f the quoins longitudinally along the side and bottom bars 35, 36 of the frame II. This sliding of the outer member or locking bars of the quoinsvIZ, I3 will cause the inclined or wedge surfaces 33 to engage with the coacting wedge surface 34 on the inner members or typeengaging bars 35, 36, commonly referred to as side and bottom sticks. The said side and bottom sticks will now move inwardly as the wedge surfaces 33, 34 ride over one another, and thus clampingly engage the type forms to lock same within the frame I I. The unlocking of the quoins is accomplished by merely turning the key in a counter-clockwise direction which results in sliding the quoins I2, I3 so as to permit the side and bottom to move outwardly, thus unclamping the type bodies.

In the modied form of the invention shown in Figures 4 to '1 inclusive, 31 designates a frame, shown fragmentarily, within which adjustable or slidable quoins 38, 39 are secured, each of the quoins 38, 39` having threadedly secured theretoy a guide pin 4I which is slidably conned in a hole or passageway 42 formed in the frame 31, whereby the quoins 38, 39 may be slidably-retained against the adjacent side or bottom bars of the frame.

The means employed` in the .present form of the invention for operatively connecting the quoins together so that both may be actuated by a single instrumentality, which may bea socket wrench or other suitable implement, comprises a pair of links 43 pivotally joined at one end by a pin 44 to the quoin 39, the other endof the said links 43 being hinged by a pin 45 to one end of a link 46 and a pair of links 41.

The other end of the pair of links 46 is hingedly connected by a pin-48 to the quoin 38, while the other ends of the links 41 are hingedly connected by a pin 49 to -a pair of links 5l pivotally secured by a pin52 to a link 53. The. links 5i, at one end, are formed with a small shoulder or cam I' which, as best shown in `Figure 4 serves to maintainV the links 43, 43 in normal locked position and, consequently, the type-engaging bars hereinaiterrementionedV in clamping engagement with the type forms. The links 41 and 5I which are hingedLtogether as at 49 constitute what might be considered a second toggle joint or equalizing Ydevice'forapplying pressure to the first toggle joint defined by the links 43 and 45 connected by the hinge or pin 45. The last mentioned link 53 is formed with an enlarged portion 54 or block servingas a plunger head and having a pin 55 secured thereto, the ends of which latterv ride in a slot 56 formed in the frame Il. A spring 51 secured in a pocket 53 is engaged against the enlarged portion 54 of the link or plate 53 and maintains pressure on the plunger head or block 55 tending to maintain the quoins 38, 39 yieldingly in the position shown in Figure 4.

The quoins 38, 39haveinclined or wedge surfaces 59 whichzare'coactingly engaged against corresponding wedge surfaces 5I formed on the type-engaging bars or. side and bottom sticks 62, 62 respectively, each of which may be considered Yas a component part of the adjacent quoin 38, 39,

so that when the quoins 38, 39 are slid in the frame by means hereinafter described, the coacting Wedge surfaces 59 and 6I will serve to thrust inwardly the type-engaging bars E2 to clamp the type forms.

By inspection of Figures 4 and 5 it will be seen the link 41 is notched as at E3 and provided with small anges or wings as at 64 in order to permit the application of a suitable key or wrench (not shown) to the said link 41 to turn or shift same in order tomove the links 43, .46 into the positions approximately indicated in YFigures 4 and 5 for shifting the quoins 33, 39 to move inwardly the type-engaging bars 52 for locking and unlocking the type forms within the frame 31. The spring 51 which serves to take up lost motion in the link or toggle-joint system illustrated, may

A.be regulated by a screw 65 threaded in an en- A.larged portion of the passageway 5S in order to maintain thedesired degree of pressure against the flange head54 and on the toggle-joint system `connected therewith. The movement of the plunger head 54, it will be observed, is restricted to the length of the small slot 55.

We are aware that the invention may be embodied in other specic forms without departing from the spirit or essential attributes thereof, and we therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
